To all who-met may concern: 7 a

I Be a known that. 1,. MICHAEL cAPe BIANCO, a citizen ofthe United States, and a resident of Glen Cove-,- inthe county of Nassau and State of New York, have invented. -a new and. Improved Adjustable rench, of which the following is a full, clear, and exact description.

This invention relates to a wrench, and has for an object the provision of a simple, strong, economically manufactured wrench especially adapted for use on automobiles.

A further object resides in the provision of a wrench which can be packed or stored away in a very small compass and at the same time is; capable of being adjusted for use in connection with a wide variety .of sizes. of nuts. 1 i

A further object resides in the provision.

of means whereby the wrench can be very simply and quickly adjusted from one position into another with aminimum expenditure of time and labor on the partof the person using the wrench.

A still further ob'ect resides the particular construction and arrangement of parts hereinafter described and claimed and shown in the accompanying drawings;

The invention is illustrated in the drawings, in which Figure 1 is a side elevation of the wrench in one adjusted position. i Figure 2 is a similar view of the wrench in another adjusted position.

Figure 3 is a plan view of the wrench.

Figure f is a transverse vertical section taken on the line l-f of Figure 1.

Figure 5 is a partial side elevation of a modified form of wrench.

Figure 6 is a front elevation of this modification.

It should be understood that the embodiment of my invention shown in the drawings is a preferred embodiment, although various modifications can be adopted in the construction and arrangement of the parts and the character of material used without departing from the general spirit of the invention as hereinafter set forth. j

The invention comprises a wrench having a handle 1, which is integrally extended at one end to form a jaw member 2. The other jaw member 2 on a pin t which is disposed through suitable apertures formed in the two jaw members. This pin is constructed jaw member 3 is detachably pivoted to the ADJ STAB E RENCH.

ini-any suitable manner so that it. can be For instance, in Figures 5 and 6 the ends of the jaw members, such as 5 and 6, are

formed to function as a socket wrench, -whereas the ,jaw members in Figures1,2, 3

andd are formed as flatsurfaces to act as an ordinary wrench. Y

on the inner faces oflthe and are; disposed pins 7 and 8. These pins extend inwardly toward each other and are. adapted to 'position the ends of aspri-ng 9 which extends from one jaw member to the" other andthe tendency of which is to keep jaw' members. 2

the jaw 'membersseparated the widest po-s;- slble distance. On the rear:oppositely'dis-f.. posed faces. of each aw member is formed.

a plurality of indentations orgrooves, such ,1 r V portions of. a link 12, which'by being disas 10. These grooves are adapted torece'ive posed in the grooves at its ends, acts as a sort of latch to restrain the'jawv members in I anyde'siredrelativeposition against the'tendenoy of the spring to disturb its position.

Consequently, it canrbe observed by consideration of Figures'l and 2'that by merely movingv the'link 12 from engagem'ent'with one pair of groovesto engagement withother grooves, the jaws may be moved relative to each other to adapt the opening between the engaging faces to any-size of article with which they are to be used. It also can be readily perceived that this manipulation of the wrench can be effected with the use of one hand alone, so that the wrench is adaptable for use under conditions where.

the operators other hand may be'busy.

. When the wrench is not in use-the link '12, the spring 9 and the pin 4 can be removed and these partstogether with the two jaw members can be packed or stored away in a very small compass so. that they are not needlessly'in the way. Furthermore, if any one of these parts breaks, a new part can be bought at a very nominal figure to replace the broken one without buying an entirelynew wrench. r j" It is apparent, therefore, that I have provided the above set forth simple, economically manufactured, strong and compact wrench capable of a wide range of' adjustv ment with a minimum expenditure of time and labor on the part of the manipulator thereof.

lVha-t I claim is:

An adjustable wrench which comprises a handle portion, a aw portion integrally connected to one end of the handle portion and extending therefromat an angle, a second jaw portion formed at one end in the form of a yoke to embrace the handle portion substantially where the handle portion connects with the first mentioned jaw portion, said handle portion having at this point an aperture, said yoke also having an aperture, a removable pin extending through the aperthe jaw portions in an adjusted position with respect to each other, said link being movable along the rows of notches to vary the distance between the jaw portions.
